Part 2 Getting Ready
This part of the manual tells you how to load batteries and the tape cartridge,
and how to perform other basic setups for the Label Printer.
Important!
• Be sure to read this section before attempting to use the Label Printer.

Power Supply

The Label Printer can be powered by six AA-size alkaline batteries or an optional
AC adaptor (AD-A95100).

Replacing Batteries

A handy low battery power indicator lets you know when battery power is getting
too low for proper operation. The message "LOW BATTERY!" appears on the
display if battery power is low when you perform any of the following operations.
• Turn power on
• Execute a print operation
Whenever the "LOW BATTERY! SET/ESC" message appears, press SET to
clear it from the display. You should still be able to perform some Label Printer
operations, but some power intensive operations (like printing) may become
impossible if battery power is too low. In any case, you should replace batteries
as soon as possible after the "LOW BATTERY!" message appears.
Important!
• Batteries can burst or leak and damage your unit if you do not use them
correctly. Note the following important points.
• Be sure that the plus (+) and minus (–) sides of each battery are facing correctly.
• Never mix batteries of different types.
• Never leave dead batteries in the Label Printer.
• Remove the batteries if you do not plan to use the Label Printer for a long
time.

Warning!
• Never use recharged batteries with the unit.
• Do not expose batteries to direct heat, do not short circuit them, and do not
try to take them apart.
• Keep batteries out of the reach of small children. If swallowed, consult
with a physician immediately.
Memory Data Backup
• Never remove the batteries or disconnect the AC adaptor (page E-9) while
the printer is turned on. Also, make sure that the display is completely blank
after turning off the printer before removing the batteries or disconnecting the
AC adaptor. Removing the batteries or disconnecting the AC adaptor at the
wrong time can cause loss of text you are working on, as well as data you
have stored in printer memory.
• Be sure to keep separate backup copies of all important data you have stored
in printer memory.
Important!
• The printer may suddenly turn off during printing if battery power goes low.
Because of this, use of the optional AC adaptor (page E-9) is recommended
to power the printer.
• Whenever switching between battery power and AC adaptor power, be sure
to first turn off the printer. Only then should you connect the AC adaptor or
load batteries. Connecting the AC adaptor or loading batteries while the printer
is on can cause power to turn off automatically, resulting in loss of text you are
working on.
Battery Life
• Printing of approximately four 18mm tape cartridges under standard print-
ing conditions*
* When printing text or graphics that contain large areas of black, and printing
under cold temperatures can shorten battery life.
